North Murderkill Hundred in Camden in Kent County, Delaware — The American Northeast (Mid-Atlantic)
The History of the Howell Mill Site
1680 Alexander Humphrey obtains title to 600 acres south of Isaac Branch. The tract is called Brecknock.
1740 John Hill builds the first mill at Brecknock.
1746 John Clayton, Jr. purchases the mill at Brecknock from John Hill.
1761 John Clayton, Jr. sells the mill to the partnership of Gregg and Hanson
1766 Thomas Hanson obtains undivided title to the mill from his partner, Gregg.
1783 Thomas Hanson dies and leaves the mill to his daughter’s children. Her husband, Samuel Howell, serves as the caretaker of the mill.
c. 1782 Through connecting power driven machinery on three floors with a complex of elevators and conveyors, Oliver Evans develops a new system of milling architecture that virtually automates the entire process.
By 1812 a three-story Oliver Evans mill replaces the small mill built in the mid-eighteenth century.
1851 Thomas Hanson Howell insures the mill and buildings with the Kent County Mutual Insurance Company. The mill was described as being a frame building (30 feet by 35 feet) and two stories high, on a brick footing. There was also a one-story “mill-house” fourteen feet square. In addition to the dwelling, the property also included a brick smoke house, a barn (16 by 42 feet) with a shed (18 by 14 feet), and a carriage house (22.5 by 25 feet).
1928 A significant hurricane washed out the mill dam.
c. 1942 The mill building is demolished and salvaged during a World War II scrap drive.
1988 Mrs. Elizabeth Howell Goggin grants the property “…upon the condition that Kent County use the land for passive park use and education, conservation, wildlife and historic preservation…”
The Steps in the Oliver Evans Mill Process
(1) Grain was brought to the mill by wagon to the entrance
(2) After weighing each sack, the miller would dump the grain into the receiving hopper
(3) Grain flowed down the chute onto the elevator, filling empty cups on their way to the attic.
(4) The elevator belt dumped the cups of grain into the grain cleaner via a chute. The wire mesh grain cleaner filtered out dirt and seeds from the grain. A second apparatus, called a smutter, removed mold, fungus, and any remaining dirt.
(5) The grain then moved from the grain cleaner to the second floor into bins, directly above the millstones.
(6) The grain traveled down through a control gate, from the bins on the second floor to the millstone hopper on the first floor.
(7) The grain was fed into the turning upper stone, called a runner
stone. A device, called a damsel, turned the runner stone against the lower stationary stone (or bed stone) at about 125 revolutions per minute. Fed through the middle of the upper stone, the ground grain made a spiral path outward between the millstones.
(8) The ground grain, or meal, fell from the outside edges of the millstone down a chute to the basement. An elevator then carried the meal up to the attic to the outer edge of the hopper boy. The grain was cooled and dried by a turning rake in the hopper boy.
(9) Another chute brought the cool, dried meal from the hopper boy to the bolter on the second floor. Meal was sorted from flour (smallest-sized particles), to middling (medium-sized particles), to bran (or largest-sized particles).
(10) These sorted grains fell down different chutes to conveyors under the second floor, moving the grain into different produce bins on the first floor.
(11) The miller packed the flour into barrels and the middlings and bran into sacks for storage or shipment.
The Mill’s Power Source
Water from the Isaac Branch provided the necessary power to run the mill. The water was collected in the mill pond.
